' YARN-CLEANING DEVICE.

Application filed June 26, 1917, Serial No. 177,007. Renewed February 14, 1921.

To (rZZ whom it may concern Be it known that I, WiLLrAM E. GoYET'rE, a citizen of the United States, and a resident of Elmira Heights, county of Chemung, State of New York, have invented a certain new and useful Improvement in Yarn- Cleaning Devices, of which the following is a specification.

This invention relates to yarn cleaning devices and more particularly to that class of devices for removing foreign matter and slubs from yarn before the latter is woven or knitted into a fabric.

One of the objects of the invention is to provide a device for the purpose specified that will be efficient in operation, put a minimum strain on the yarn and thereby avoid breakage of the yarn, and which will remove the objectionable matters from the yarn in such a manner as will largely eliminate sudden shocks or erks that might break the yarn.

Other objects and the features of novelty will be apparent from the following description taken in connection with the accompanying drawings in which- Figure 1 is a side elevation of a device embodying the invention;

2 is a top plan of the same;

Fig. 3 is a section on line 33 of Fig. 1; and

Fig. 4 is a section on line 4-4 of Fig. 3.

Referring to the drawings, 10 indicates any suitable frame which will be attached to the frame of a machine, with which the invention is to be used, in any preferred manner as, for example, by means of screws in openings 11. A depending arm 12 of the frame, carries a tension device 13, the character of which may be varied to suit dif ferent conditions, this tension device not constituting a part of the present invention.

The frame 10, carries one or more studs 14, and in the form illustrated there are two of the same on which the grooved pulley wheels 15 and 16 are mounted. In this construction the wheels 15 and 16 are each mounted on a tubular shaft or sleeve 17 and these sleeves also have secured thereon brushing or cleaning wheels, which are indicated at 18 and 19. These wheels 18 and 19 preferably have knurled or toothed pe ripheries which contact with the yarn, as hereinafter described. Each of the sleeves 17 constitutes a rigid connection between Specification of Letters Patent.

Serial No. 445,012.

the Wheels thereon and as a guard to prevent the refuse from getting back onto the yarn I provide, between each cleaning wheel and its grooved pulley, a disk or flange 20. The sleeves 17 are held in position on the studs 14 by means of screws 21.

Arranged on the frame 10, adjacent the wheels 18 and 19 and partly surrounding the latter are the stationary cleaners 22 and 23, the construction of these being shown in detail in Figs. 3 and 4. Each of these stationary cleaners is secured to frame 10 by screws 24, and as shown particularly in Fig. 4 conforms closely to the periphery of the cleaning wheel, only slight clearance being provided between these parts. The cleaners 22 and 23 are slotted at 25 to receive the yarn, the slot cutting through the projecting ends 26 and extendipg to the line 27 which represents the bottom of the slot. The lower edge of the cleaners 22 and 23 is beveled on opposite sides as indicated at 28 and 29.

ssoc'iated with each of the wheels 18 and 19 is a guide block 30, which is secured in position by a screw 31, and in order to ermit the block to be adjusted the hole t erein,

for the screw, is made larger than the screw, as indicated at 32. Th frame 10 has arranged thereon the fixed guides 33 and 34 for the yarn.

The passage of the yarn through the mechanism is shown in Fig. 1, the yarn being indicated at 35 and moving in the direction of the arrows. After passing the tension device 13, the yarn passes over the grooved pulley 15, then over grooved pulley 16 and either again over pulleys 15 and 16 or from pulley 15 to the guide 33, whence it passes across the cleaning wheel 18 and through the slot 25 in the stationary cleaner 22. Next the yarn goes across the cleaning wheel 19 and through slot 25 in th stationary cleaner 23, from which it passes around the guide 34 and out of the device.

It will be observed from Fig. 3 that the grooves in wheels 15 and 16 are of smaller diameter than the peripheries of the cleaning wheels 18 and 19 and as the yarn in passing around wheels 15 and 16 turns theseand thereby actuates the cleaning wheels, the latter will move relatively to the yarn and have a brushing action thereon. The

course of the yarn is such that the cleaning ripheries of the wheels having a different velocity than the yarn, the wheels Wlll loosen and brush off any foreign matter or slubs,

the stationary cleaners 22 and 23 cotiperating with the wheels and preventing the refuse from being caught and carried away by the yarn. The removal of such refuse from the yarn is therefore effected without subjecting the yarn to jerks or excessive strains as is the case of cleaning devices heretofore used, and where the cleaning wheels have a greater velocity than the yarn, the refuse is accelerated and not only removed from the yarn but is also instantly thrown out of the cleaning device. This action of the cleaning wheels prevents the refuse from getting back onto the running yarn and also renders special collecting devices for the refuse unnecessary. The teeth or projections on the cleaning wheels work into the fibers of the yarn and refus that is not actually removed by the wheels is brought into position to be intercepted by the stationary cleaners 22 and 23. On account of the arched under surface of these stationary cleaners the foreign matters in the yarn run along this arched surface and are thereby. gradually withdrawn laterally without a sudden jerk on the yarn as is the case of cleaners heretofore used and wherein the foreign matters are suddenly stopped by some intercepting device. The bevel surfaces 28 and 29 facilitate the clearing of the device of the refuse removed from the yarn.

The actuation of the moving parts of the device by the yarn itself has the advantage of insuring automatic stoppage of such parts whenever the yarn breaks and thus avoids possibility of delay and waste of yarn through the entanglement of an end in a moving part. i
